Resurvey of Byrd Station drill hole, Antarctica
AbstractDirectional surveys of the borehole at Byrd Station, Antarctica were made in 1968, 1969, 1975 and 1988. The sensitivity and accuracy of the survey tools used for the first three surveys were less than that used for the 1988 survey. The 1988 survey confirms earlier surveys and supports the conclusion that there has been little deformation in the Holocene ice comprising the upper 1000 m at Byrd Station and that, what deformation is occurring, is taking place in the Wisconsin ice beginning at 1200 m depth. Position measurements in 1972, 1973 and 1988 with satellite navigation equipment show that the surface velocity is 10.9 m yr−1 in the direction 220°.
